47. The expert from AVERE introduced ECE/TRANS/WP.29/GRVA/2021/7, a revised amendment proposal to the Automatically Commanded Steering Function (ACSF) of Category B1 provisions in UN Regulation No. 79 (maximum lateral acceleration aymax). The expert from the Netherlands opposed to the proposal, as it could generate mode confusion and overreliance on the market. The experts from France, the European Commission and UK supported the proposal. The expert from Germany suggested that the proposal is further discussed by a task force. GRVA agreed to keep the proposal on hold. |
